It hasn't even been a full month since we saw the release of the Catalyst 9.3 driver, but here we are with 9.4. Given the short time-frame between each release, this one isn't filled to the brim with new features, but there are a few things to point out. First is the revamped OverDrive utility, which AMD states will accurately determine the "best" overclocked Core and Memory frequencies for any HD 4000 series card.

We can assume that this revamped tool will be a little more accurate than previous versions, or else it wouldn't have a reason to make it into the "what's new" list in the driver's PDF. Given that the HD 4000 series, especially the HD 4890, overclocks so well, it does make sense that the tool was given a little love. Of course, it's still unlikely to appease the overclockers who don't mind pushing their cards to their breaking point...but AMD does have to make sure they don't go breaking things on people.

Also new in 9.4 are a few bug fixes, which include an issue with World of Warcraft, where flickering would occur when the Shadow setting was set to medium or high while using CrossFire. Other fixes include Google Sketchup's blank screen issue, the ridding of artifacts for Age of Conan in DX10 mode and better support for HDMI connections using resolutions above 10x7.

That's not all though, so you might want to check out the official release notes (PDF) to see what else has been altered. You can also download the latest driver from the AMD Game website here.

ATI Catalyst 9.4 includes a new ATI Overdrive auto-tune application finds over-clocked engine and memory values for ATI Overdrive supported ATI Radeon Graphics accelerators. This new added support is designed for the ATI Radeon HD 4000 Series of GPUs. We work hard to deliver the best platform solutions that consist of CPU and GPU. As the only company in the industry that can deliver both we have the unique opportunity to develop free software to optimize performance across AMD-based platforms.
